Epigenetics Alert! UStream "Office Hours" with Duke's Randy Jirtle today at noon EST

Here's a great, last-minute opportunity to interact one-on-one with a major player in the field of environmental and dietary influences on gene expression. From the Duke University Office of News and Communications:

Duke Professor Randy Jirtle will discuss epigenetics and answer viewers’ questions during a live “Office Hours” webcast interview at noon (17:00 GMT) Friday, Jan. 22, on Duke’s Ustream channel.

To ask a question of Jirtle in advance or during the session, send an email to live@duke.edu, post a comment on the Duke University Live Ustream page on Facebook or tweet with the tag #dukelive.

The science of epigenetics explores the molecular activity that influences the expression of genes. Jirtle emerged as a pioneer in the field with a 2003 study in which he showed how the genetic expression of a baby mouse’s fur color could be altered by changing its mother’s diet during pregnancy. Recent stories on epigenetics by NOVA, Time and the Washington Post have cited his research. Jirtle’s lab chronicles developments in the field on the Geneimprint website

Epigenetics. You keep using that word. I do not think it means what you think it means. I realize I overuse that little joke, but I can't help but think that virtually every time I see advocates of so-called "complementary and alternative medicine" (CAM) or, as it's known more commonly now, "…
